Under Independent Variables select Temperature as Variable 1.

Next, double click on Property Table-1 to open the property window. In the Select Process Stream window that appears, select STEAM and press OK. In the navigation pane, go to Stream Analysis and click on the dropdown arrow next to Add and select Property Table. Rename this stream STEAM and enter a Mole Fraction of 1 for water. Double cli ck on the stream to open the property window.

Select NBS Steam as the property package.Īdd a material stream to the flowsheet from the Model Palette.

In the Fluid Packages folder, select Add. Add Water to the component list.Ĭreate a fluid package. In the Component Lists folder, select Add. Select New to start a new simulation.Ĭreate a component list. We would like to create a table that displays mass enthalpy, mass entropy, pressure, and density. Problem Using Aspen HYSYS, we want to calculate saturated steam properties from 100☌ to 300☌. They may may not reflect an industrial application or real situation.Ĥ. The examples presented are solely intended to illustra ill ustrate te specific concepts and principles.

The maximum maximu m pressure press ure is over ove r 10000 10000 bar. Use the NBS Steam property method for pure water and steam with temperature te mperature ranges of 273.15 273.15 K to 2000 2000 K. The NBS Steam Ste am property methods uses the: 1984 1984 International Associat A ssociation ion for Properties of Water and Steam (IAPWS, )) correlations for thermodynamic propertie prope rtiess  These correlati correlations ons do not provide continuity at the boundaries, which w hich can lead to convergence problems and predict wrong trends. Note The ASME Steam property method uses the: 1967 1967 International Associatio A ssociation n for Properties of Water and Steam (IAPWS, )) correlations for thermodynamic propertie prope rtiess ĪSME 1967 1967 STEAM-TA STEAM-TA method is made up of dif ferent correlations covering dif ferent ferent regions of the P -T space.
